Help removing Active Sky

I had Active Sky 2012 and I uninstalled it yesterday. After installing it I restarted my computer and went back to FSX and when I pressed SHIFT+5 a blank HiFi Technologies radar came up. I went in and manually removed all the flies that are from Active Sky and HiFi Technologies and it still does it. I found out that it is called xGuage and I looked to see if there were any files with that name and there were not. So I would love to get this completely uninstalled so that SHIFT+5 pulls up what it is supposed to.
